J'OURNAL-BOX-COOLING ATTACHMENT.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed October 25, 1916. Serial No. 127,674.

To all whom it may concern:

Be it known that I, RAYMOND B. HARRIS, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of lVisconsin, have invented a new and useful J ournal-Box-Cooling Attachment, of which the following is a specification.

lhis invention relates to an attachment for use in cooling journal boxes of railway cars.

Various means have been devised heretofore for the purpose of cooling journal boxes but they have always been found objectionable. For example, where water has been used for this purpose, it has been found that the same freezes during cold weather and thus the flow of the water into the journal box is stopped.

One of the objects of the present invention is to provide means whereby ice can be supplied to the journal box and thus the cooling of the box can be effected at low temperatures without danger of the apparatus becoming clogged as where water is used and the same freezes.

A further object is to provide a cooling attachment which can be applied readily to an ordinary journal box and which is simple, durable and compact in construction.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a vertical section through the attachment constituting the present invention, the same being shown applied to a journal box, a portion of the car structure being shown in section.

Fig. 2 is a side elevation of the mechanism shown in Fig. 1.

Referring to the figures by characters of reference 1 designates a portion of a car structure and 2 designates a journal box such as commonly employed, this box being provided with the usual hinged lid 3. The attachment constituting the present invention includes a tube A the lower end of which is bent downwardly and inwardly as at 5 and has spaced ears 6 and 7 at the lower free end thereof, one of the ears carrying a binding screw 8. A collar 9 is mounted upon the upper portion of the tube and has opposed cars 10 from which extend fastening chains 11 or the like which are designed to be secured to the side of the car 1.

lVhen a bearing becomes overheated and it is desired to cool the same, the lower end of the tube 4: is inserted into the opening in the outer side of the journal box, ears 6 and 7 being placed at opposite sides of the wall of the box and the screw 8 being clamped upon said wall. The chains or other fastening devices 11 are then secured to the side of the car structure preferably by extending them through staples or loops 12. With the parts thus secured, ice broken into small pieces is placed in the tube 4: and will gravitate into the box 2. No matter how cold the weather may be the ice will gravitate within the tube and be automatically fed to the journal box. Consequently the structure will not be rendered inactive because of freezing weather, as would be the case should water be used as a cooling medium. By mounting the tube in the manner set forth, any relative movement of the car body and the truck will not injure the attachment. After the attachment has been placed in position the car can continue its journey without further attention.

/Vhat is claimed is 1. A device for cooling journal bearings, including an ice receiving tube having open ends, one of said ends being insertible into the journal box, means upon said end portion of the tube for engaging the wall of the opening in the journal box, means for fastening the tube to said box, and flexible means for connecting the upperend of the tube to the car body, said means including a collar upon the tube, and flexible elements extending in opposite directions from the collar.

2. The combination with a car structure including a journal box having an opening therein, and a car body above the box, of an ice receiving tube arranged outside of the car body and having its lower end extended into the opening in the journal box, means upon the lower end of the tube for engaging the wall of the opening in the journal box, means for fastening said end of the tube to the journal box, a collar upon the upper portion of the tube, and oppositely extending flexible elements secured to the collar and detaohably fastened to the car body.

In testimony that I claim the foregoing as my own, I have hereto allixed my signature in the presence of two Witnesses.
